[Resolved] Mailspring 1.14 won't launch on macOS High Sierra

Help
#1

I have a mac version 10.13.6 High Sierra. My version of Mailspring is 1.13.1
It automatically updates to version 1.14, which I cannot open on my Mac because it is old. How can I prevent it from updating automatically? Where can I find older versions of Mailspring?
Thank you

You find old version of Mailspring on GitHub.

Thanks. I’ve done that. The problem is that with version 1.13 it updates automatically every time I close it, and I have to reinstall it every day. Is there a way to disable the automatic update? I didn’t find one.
Thanks for everything.

Hey folks, thanks for reaching out - I believe that this was due to an issue with the Mailspring 1.14.0 release builds. If you try upgrading again it should work properly now, we haven’t deprecated support for High Sierra.

Thanks!

Thanks for the reply.
When I update to version 1.14 I get the following message and I can’t start
“You have macOS version 10.13.6 installed. This app requires macOS 10.15 or later.”

Thanks!

Hey! Sorry for the delay, I expect this will happen to more people soon because Chromium and Electron are both moving off older versions of macOS, High Sierra was first and I think Mojave support will be dropped soon.

I’d recommend using a tool like Little Snitch on your machine to stop auto-updaters. (It may be helpful for other programs as well, and it’s nice to disable them all in the same way). For Mailspring, if you can stop it from reaching updates.getmailspring.com, it will stop trying to auto-update.

Sorry for the hassle!

I can’t find the old versions of Mailspring on GitHub. Where do I look?
I have an old iMac, that won’t update the OS past Catalina.
Appreciate any help.

Where on GitHub? I went there and found nothing.

with the latest version, this bug is re-introduced - macOS Catalina - 10.15.7 is no longer working with the latest mailspring version, still it updates to the latest version and becomes un-useable.

How can I stop/disable the auto-update?

UPDATED INFO FOUND

Just found the firewall rules - updates.getmailspring.com must be blocked so the old version 1.14.0 will not update.

Version 1.13.2 does work on High Sierra.
When it asks to update, just say no and that’s it.
